ENGINEER'S GUIDE
Congratulations! You've just purchased the most
feature-rich and technically advanced HO Steam

on any other HO scale steam, including smooth
performance from a three-scale-mile-per-hour crawl
to full throttle; "cruise control" for steady speeds
regardless of curves, switches and grades; built-in
decoders for DCC and the M.T.H. Digital Command
System (DCS); and a full range of prototypical
sounds. If you're looking for motive power that's
accurately detailed, smooth running, and a great deal
of fun to operate, it doesn't get any better than this!
